Engine rebuild question

bikebuilder42

I am currently rebuilding a 2004 YZ450 i am about 40% done with the motor however I came across what looks to be a dowel hole between the 2 shifting forks in the transmission. If im not mistaken I remember a dowel going there, however when i put the two cases together there seems to be no need for a dowel because they dont meet. I have looked in the manuel but i can't seem to find anything pertaining to this can anyone shed some light on this I have attached 2 picture with my finger pointing to the hole i am talking about, hope you can see it.
